Has anyone else had a negative experience with Impact Outsource?

I went for an interview with this company, after sending them a resume online. After my initial interview I was invited back for a second interview which took place "in the field". The second interview lasted from 11:00am until 8:30pm, 9+ (unpaid hours) which consisted of knocking on doors in an attempt to raise money for one of their clients. Has anyone else gone for an interview with this company? Was your experience similar to mine, or was I the only one who wasted a day on them?
